Is anyone building the KGSSHV? - Page 18

The amp is fully balanced like most stat amps, you will get a balanced output even with a single ended input, it doesn't matter.

A short to ground from inputs shouldn’t cause this problem. The outputs on the other hand.....

Not exactly.  Se input to balanced output causes a differential gain of about 2%.

 

Balanced input is much better for stax amps.

Highly recommend going either the TKD route or spring for the Penny and Giles RF15 or ALPS RK50.

 

There is the KG attenuator as well if you can lay your hands on one which would work out to about $220-250 i believe.

Anybody knows where to buy the quad penny & giles?

Call them.

Just make sure that the source is actually balanced.  Way too many designers have used SE output stages with nasty opamp phase splitters to drive the balanced outputs.  This is also true of some very expensive gear...

The Matrix uses a phase splitter, it's going up on ebay, ignorance was bliss. blink.gif

Got a refund on the Matrix, back to the original plan building the Buffalo Dac.

 

Anybody know how good the Joshua Tree is? http://www.twistedpearaudio.com/control/jt.aspx

 

And how well it would be with the KGSSHV.

joshua tree is very good.  Not constant impedance, which is just plain stupid.

DACT installed, floors the Khozmo is every aspect.

Very nice. Would you mind posting a closer picture of the DACT connections and also the Stax jack?
I see you grounded your pot directly to the star ground.
Some people have recommended not to because the body is already grounded directly to the ground panel.

Nice clean build

Thanks guys!

There’s really nothing in it, as both positions (star ground and the DACT body) have the same potential.

So it's still good although it doesn't have constant impedance?

I like amb's thing better.
Both are going to be too big for your chassis.
